| description | The invention discloses a sliding block type concave mould friction non-riveting connection method of a lightweight plate. The sliding block type concave mould friction non-riveting connection methodcomprises the steps that a to-be-riveted part is subjected to partial frictional heating through the rotation of a friction head and an upper punch; then the friction head stops rotating and applies blank holding force to the to-be-riveted part, a pressing head enables the upper punch to move downwards under the action of a punching power source, metal of an upper plate and metal of a lower plateflow into a mould cavity of a lower mould, sectioning sliding blocks of the lower mould are forced to flow and expand in the radial directions, the metal of the upper plate and the metal of the lowerplate continue to flow to gaps between the sectioning sliding blocks and gaps between the lower punch and the sectioning sliding blocks till the mould cavity of the lower mould is filled, and an S-shaped mechanical lock is form |
